maritime explosion proof intercom
Maritime explosion-proof intercom is a kind of safe and reliable communication equipment specially designed for personnel working in maritime environments containing flammable and explosive gases or dust. Maritime explosion-proof intercoms usually need to comply with international or national explosion-proof standards, such as ATEX or IECEx, and have high-level waterproof performance, such as IP67 or IP68. So, how to choose a maritime explosion-proof intercom?
Explosion-proof level: The explosion-proof level refers to the ability of the walkie-talkie to be used safely in different explosion-risk areas and different explosive gases or dusts. The explosion-proof level is divided into three levels: IIC, IIB and IIA. The IIC level is high and can be used in the most flammable gases such as hydrogen, while the IIA level is low and can only be used in less flammable gases such as methane. use. According to the specific conditions of the workplace, choose an intercom with an appropriate explosion-proof level.
Waterproof level: The waterproof level refers to the ability of the walkie-talkie to work normally in different water depths and water pressures. The waterproof level is divided into eight levels from IPX0 to IPX8. The IPX8 level is high and can work in water depths of more than 1 meter for a long time, while the IPX0 level is low and cannot be waterproof. Choose a walkie-talkie with an appropriate waterproof rating based on the water depth and water pressure that may be encountered in the workplace.
Communication distance: Communication distance refers to the distance at which the walkie-talkie can make clear calls without obstacles. The communication distance is affected by factors such as the transmitter power, frequency, antenna, and battery of the walkie-talkie. Generally speaking, the higher the transmission power, the longer the communication distance, but it will also increase the battery consumption and the volume and weight of the walkie-talkie. The higher the frequency, the better the communication quality, but it will also be affected by more interference and obstacles.
The longer the antenna, the better the communication effect, but it will also increase the size of the walkie-talkie and make it less portable. The larger the battery capacity, the longer the communication time, but it also increases the weight of the walkie-talkie and the charging time. Choose an intercom with the appropriate communication distance based on the specific needs of the workplace.
Other functions: In addition to the above basic performance requirements, maritime explosion-proof walkie-talkies can also have some other functions, such as floating function, emergency call function, digital analog compatibility function, voice encryption function, noise suppression function, scanning function, programming function, etc. These functions allow you to choose the walkie-talkie you need based on different work scenarios and personal preferences.
